9 Claims. (Cl. 242-434) The present invention relates to a wire reelin apparatus. 1 1 1 1. 1

More particularly the invention relates to a wire windingreel selectivelyroperable for high or low speed winding. 1 1 1 In the reeling or wire, there are presently known many systems for effecting such operation, each of which has itsown particular advantages and which are also accompanied by certain disadvantages. The difierent systems operate with different winding velocities, thus while a system with a low wire winding velocity possesses the advantage that'the wire isnot twisted, low winding speed is a drawback. i 1

Other systems having higher wire winding velocity are operable to increase the speed of op-Q eration but are peculiarly limited to wires of circular section since there is a possibility of twisting a wire about its axis when winding at high speed. 1 1 p Accordingly and "as previously indicated, the present invention has for an object to provide a structural unitenibodying. componentsselec'tively operable for either high or low speed winding.

More particularly the invention has for an object to provide a compact structure, including an inner reel and an outer reel drum coaxial there with disposed on a vertical axis with pivoted wire coilsupporting arms operably associated 'respec tively internally and externally of the elements for movement into supporting position beneath the space between the reel and drum and selec tively operable depending upon whether A further and more specific object is to provide a compact wire reeling machine capable of operating in accordance with either of the wellknown Garret or Edenborn reeling systems.

,The inventionwill now be described with reference to the accompanying drawings, in which:

Figure 1 illustrates an embodiment of the invention partly in section and partly in elevation;

Figure 2 is an enlarged detail of a portion of Figure 1 partly in section and partly in elevation; and

Figure 3 is an elevational view of the embodiment illustrated in Figure I viewed from a different side thereof and partly illustrating the drive for reciprocating the central feed tube.

In connection with the present invention the structure is particularly applicable to the Garre and Edenborn reeling systems.

In the Garret system the reeling apparatus includes the rotatable reel with the wire "to he wound supplied from the side and wound on the high or lowwinding speeds are utilized. 1

external surface of the rotatable reel, movable supporting arms are utilized to support the coil of wire while it is being wound. In this system's. low wire velocity of between 3 'tolO motel-sis Inthe Edenborn system there is again provided a reel mounted on a vertical axis between which is fixed a feed tube having an upper part that is coaxial with the reel and a lower part at an angle theretoof about and terminating :at the periphery of the reel. 'The 'feed'tube is rotated. with the wire fed 'therethrough and by means-oi rotation of the feed tube about a vertical. axis a coil of wire is built up on arms that support the same positioned at' the bottom or the reels 1nthis construction winding velocities "up to 25 meters are obtainable so that the capacity of thisreel-is substantially-greater than a reel operating under the Garret system. 1 1

The present invention particularly is "applicable to these two reeling 'systems and by itsstructure permits selective high or low speed operation.

Referring to the drawing, a name work I of sectional steel supports "a cast iron reelhousing 2' provided with an internal annular water tank 3. The housing is centrally ap'ertur'ed andsupports a tubular shaft! which is set into 'rotationby a. main motor 1 which drives a pinion flmeshing with 'a'ge'ar 5 "spline'd to the shaft. 'At the lower end or the tubular shaft 'a sleeve 8 is fastened which serves as a releasable "coupling and which supports a frusto-c'oni'cal reel 9. 5 An intermediate Tpiec'e I0 is arranged forlongitudin'al displacement on the 'tubular shaft and has screwed into its lower end a control rod it. This rod acts on a sleeve [3. which can be displaced on the lower end l2 of the tubular shaft. A plurality of supportingbell-cr'ank arms I! "are carried by the drum. Onthe left-hand side "of the shaft endjVIZ, these supporting: arms are shown in operative position under the: action or thesleeve 13 whilst on theright hand :side the inner arms H are shown to be rotated so as toli'e within the periphery or thereel drum. AnEde'nborn feed tube l5 havinga funnel-shaped mouth I 6 is inserted in the upper end of the intermediate piece Ill. An 'Edenb'orn guide tube i1" is insorted in the intermediate piece at an angle of 45". A curved passage l a 'rormeujin t'heinterm'e diate piece ,effects a connection betweenthe tubes 15 and H. An outer drum T9 surroundin the reel 9 forms a page 20 ror'th'e reception or the wire coil.

i The outer drum is "formed with an e ternal oonicalseat 2-! 'which hg'a'g'e's'wlth acorrespond ingly shaped braking surface 22 provided on an outer ring 23 in the withdrawn position of the inner arms I4. This outer ring is rigidly connected to the housing 2 through tie rods 24 and tubular distance pieces 25 and carries one-arm outer supporting arms 26 of the Edenborn type. The outer arms 26 are actuated by racks 21 slidably mounted in the ring 23. As shown on the right-hand sideof the drawing the outer arms 26 are swung in position below the storage space 20, whilst on the left-hand side the outer arms 26 are shown to be swung out of the way when the arms I4 are in use.

The racks 21 are provided on the ends of rods which are guided for longitudinal telescopic displacement within tubular lower portions 28 of spring housings within which are also mounted internally springs 29 and 30. These springs cooperate with head means provided on the end of v the rack rods to resiliently hold these rods and the'racks in a mid position, while leaving the rods and racks free for slight'displacements in either direction. A strong compression spring 3| which is held between the cap closure 32' for the spring housings and the bushing 33 mounted in the bores in the housing 2 that receive the spring housings insures that the racks2'I and the spring housings, including the tubular portion 28, always occupies their lowermost position. There are six racks in the present embodiment, some of which are not shown; As particularly "illustrated in Figure 2, the upper portions of :the spring housings are solid rods that journal rollers 34 mounted on bolts 35 secured transversely of the axis of these rods. Theserollers ride on cam surfaces having high points as at 39 and which surfaces are formed on an annulus 31 which is provided with internal teeth 38. This annulus is driven by a motor 40 which drives a pinion 4| meshing with the teeth 38. Thus upon rotation of the annulus the cam surfaces simultaneously elevate the spring housings in the racks connected thereto. Figure 3 illustrates theinvention in the elevation with particular reference to the drivepfor the second reeling arrangement; A third motor 42 having a worm drive is here provided which through a sliderv crank mechanism .43 moves the feeding tube 1 or'reel shaft respectively and thereby the inner arms I4. The motion is effected through a one-arm lever 44 the pivot 45 of which is mounted on a slidably-arranged sleeve 46 subjected to the action of the spring 41." A removable auxiliary feed tube for Garret type operation as illustrated at 48 and "beneath the storage space 20' and supported by theframework. I is a cooling grid 49 of known construction.

The mode of operation of the apparatus above describedis as follows:

When the apparatus is to work on the Garret system, the removable auxiliary Garret type feed tube 48.. is placed in position, the arms 26 arev moved 'out of the way as shown on the left-hand side of Figure 1, by actuating racks 21, and the guide tube I! is removed. The arms I 4 are moved upwardly to takeup their positions below the storage space 20,- this being effected by lowering the intermediate piece I0 through the feed tube I6 and the slidercrank mechanism 43. At this time the reel 9 is coupled through coupling 8 to the hollow shaft 4 and is maintained in rotation. By actuating the crank 43 and the members In, II, l3, I4 and I6 associated therewith the arms I4 are withdrawn and the complete coil of wire is ejected, following which the inner arms I4 are moved-back into position below the storage space.

The coil of wire is dropped on to a cooling grid 49 of known construction which is directly supported by the framework I and another coil is formed.

If the apparatus is to operate on the Edenborn system, the Garret feed tube 48 is removed and the operating means for the inner arms I4 are displaced upwardly so that these arms are tilted away from below the storage space. In this position the Edenborn guide tube IT can be mounted on the intermediate piece I0 and fixes the latter in position. At the same time the racks 21 are movedinto their lowermost position so that the storage space is closed and the reel drum is uncoupled and remains stationary. After a coil of wire has been completed by rotation of the hollow shaft 4 under the action of the motor I, by

setting into motion the motor 40, the outer arms 26 are successively retracted from and returned to their position below the storage space. The coil of wire again drops on to the cooling grid 49.

It will be understood that the apparatus described may be subjected to numerous modifications and additions without exceeding the scope of the invention. The uncoupling of the reel 9 may, for instance, be effected automatically by driving upwardly the intermediate piece I0. For a rapid discharge of the coil of wire it is immaterial whether the reel 9 is driven or not and when the reel is again coupled to the driving shaft its speed of rotation will not have appreciatively decreased.

The braking of the reel may be effected simultaneously with the moving into position of the outer arms 26 either by the ends abutting against the edge'of the drum or by means of a special brake for the drum.

The outer drum I 9, which is lifted by the inner arms I4 may be driven thereby whilst inversely on moving the inner arms I4 into position the outer drum islowered and with its brake surface comes into contact with the outer ring and is thus brought to rest. It is moreover possible to proceed in a difierent or, for instance in the reverse way.
